If you have started using a Macbook after a Windows machine probably you are frustrated with the Trash. In Windows you can easily delete single files from your Trash forever by simply pressing Delete button after you choose the file. In Mac OS though it is not that easy because Mac OS doesn’t want you use the Trash as a depository for your unwanted files. It keeps the files in the Trash in case you delete a file by accident and want to put it back. You can empty your whole Trash but you are not allowed to delete the files one by one… I mean you are not allowed to do it from the Trash but there is a back door of course ðŸ™‚
Open the Terminal which is under Launchpad>Other or Launchpad>Utilities. A new window will appear with some weird alien language written in it. Type the following phrase
Now your file named “filename” is gone. By the way you need to type the filename with its extension like rm .Trash/Emrevideo2.mp4
A small advice; arrange the files in the Trash according to their Size. This way you can see the biggest files that you definitely want to get rid of for more hard drive space and before you delete a file, give it a different and easier name, something like aa.mp4 It will be easier to type the file’s name in Terminal.
Many people think computer mouses will vanish from our desktops very soon due to wide usage of touch screen devices. I can’t say I fully agree to this idea but it is a fact that touch screens are shaping the technological developments. Recently I encountered with an interesting product which made me rethink the definition of “computer mouse”.
It is called Flying Fingers and it is basically a wearable computer mouse. At a first glance it seems like one of those “cool” gadgets but actually it is more than that because it is totally functioning in a different way than traditional mice.
The main difference is the 3-Dimensional use of the device. Traditional mice on a flat surface have a 2-Dimensional movement but Flying Fingers is used in air which means the cursor on the screen can have a depth of field. The cursor can now move inside and outside the screen. Can you imagine combining this feature with 3D screens? You might say “We don’t have that technology yet so it won’t make a difference in 2D screens” but that’s not the fact. Flying Fingers have the potential of converting 2D screens into 3D and this will change many popular games, office products, applications and software we are using. For example you don’t need to touch the screen anymore to throw birds onto pigs ðŸ˜‰ and moreover the sling doesn’t have to be 2D anymore. Also while slicing fruits Flying Fingers make you feel like you are using a Katana.
I used Flying Fingers in my lessons and I can say that it helped me a lot in classroom management. The first day, when I entered the classroom my students’ first reaction was saying “Get well soon” because they thought I hurt my hand and wearing a special glove. When I explained them what it is they were stunned. Some of them started talking about the movie Minority Report so I had to make a small presentation before I start the lesson.
After using Flying Fingers for a week I took some notes;
How It Can Assist You During Lesson:
The major role of FF is giving you the freedom to walk around the classroom and to use your computer anywhere. Also it is a very helpful presentation mouse.
- If you are using interactive white board, you can control all features without being present in front of the board.
- Even if you don’t have an IWB you can still use your computer (opening a file, showing a webpage etc.) without staying next to your computer.
- Routine tasks like opening and closing a file, copy-paste, highlighting a text, surfing in the web, pausing and playing a video can easliy be done.
- If it is supported by new software it can be an essential teaching tool. For example when working with 3D object animations you can move your cursor not in 2D but in 3D which can give you the sense of holding that object physically.
Things To Consider While Using FF:
- Getting used to calibration takes some time.
- The communication between the device and its USB dongle shouldn’t be interrupted.
- I used On/Off button a lot because when it is open the cursor keeps moving while writing on the board and it is frustrating.
- In the beginning I pushed the buttons placed on the glove accidently while writing something on the board but I got used to it quickly and never happened again.
Possible Future Features:
- I have a presentation mouse and it has a laser on it which I find very helpful so I think FF has to have a laser pointer soon.
- It is not possible to write on air, which is understandable, but still everyone wants to see that happen J
- This feature is not possible yet but I believe in the future it can track hand movements (in detail) while writing something on a regular paper and record it electronically.

Whether you are using Twitter for educational purposes or not you might want to save your tweets for future. According to experts life of a tweet is approximately 30 minutes. This means when you share something amazing, useful, shocking it will be lost in the deep waters of Twitter. Wouldn’t it be wonderful if you could save your tweets and reach the content whenever you want? This way you can share your messages again. There is a practical way to do this. You can simply archieve your tweets under Settings menu.
This method is fast but not very efficient. I personally would like to have my tweets in a spreadsheet or in a word processor. Currently there are lots of tools which can do that for you but I don’t use any of them. I use IFTTT – If This then That which is simply this:
IFTTT is not only for Twitter. It can be used for many websites and apps. I have created following connection – called recipe for myself: If I tweet, then a row to a spreadsheet in my Google Drive is automatically added. I have also created this recipe: If I tweet, then it is appended to a document in my Google Drive. With these recipes my tweets are automatically stored in a Google Spreadsheet and in a Google Doc. With IFTTT it is possible to create different recipes and connect Twitter to other services such as LinkedIn.
What I like in IFTTT is it is a versatile system. There are lots of possibilities and you are limited to your imagination. For example there is a recipe in which you get a notification to your Android device when an astronaut enters space! If you are interested in IFTTT go to ifttt.com and start exploring recipes which will ease your life but first don’t forget to download the app to your mobile device from here https://ifttt.com/mobile
In this short article I’d like to share an idea that came to my mind while I was playing Call Of Duty Black Ops. Things I’ll share might disturb some people but my intention is to create a discussion and find a common sense.
COD is a first person shooter game. When you open the game you see a gun in your hands and you are expected to kill as much people as you can. This game is not for kids and on its cover you can see that it is for people older than 18 but I think this game, or let’s just say some part of this game can be used for educational purposes. Let me provide some details;
– There are 2 teams in the game.
– In each game teams are given certain tasks. For example they try to capture each other’s flags or they try to capture certain points in the map etc.
– The game has different maps. One of them is called Nuketown and this map forced me to write this article. If you keep reading you’ll understand the reason.
– Players can have multiple weapons and they make their choices according to personal talents. If you have good reflexes you can choose to have knife and engage in a close combat, if you are patient enough you can choose to be a sniper.
Up to this point nothing seems special but let’s imagine this: you take your high school students to computer lab where COD is installed in each computer. They form two groups and wait for your instructions. You tell them the type of the game and give them a visual of the map. Then you give them some time to discuss their strategies. An incredible collaboration session starts. Each member of the team is evaluated, questioned, given small tasks etc. After discussions they start playing. At the end of the game one team wins but what were the factors that took them to victory? It’s time to discuss the result. What strategies did they follow? What were the things they couldn’t foresee? What will they do different next time? Just by focusing on the strategic side of the game only can you see the resemblance of these two games?
On one side there is blood, violonce and addiction possibility. On the other side an opportunity to teach strategic thinking, teamwork, collaboration, communication and many more 21st century skills. It is a fact that many kids under 18 are playing these games and their parents are very concerned. They fear that these games will turn their kids into a killing machine. Maybe we can’t put these type of games into school system but instead of turning our backs to the fact can’t we at least guide parents or share some (possible) practices or do something else?
I often see phrases like “Technology is a tool not a learning outcome” – “Pedagogy is the driver technology is the accelerator” and many more hanging around at conferences, in websites and in social media. The purpose of all these slogans are same; relieving teacher’s minds. As you know there exists a solid resistance in teachers when it comes to integrating technology into education. Tech leaders are trying to convince them that the process is not that frightening, hard or inefficient. Although they are showing goodwill I usually see that they can not reach teachers as much as they want to. The reason to that is very simple; both parties do not speak the same language and have different point of views. A great majority of tech leaders are not classroom teachers and they can’t fully understand that as a teacher my priorities, my concerns, my agenda are very different than theirs. If they want to convince me on something they should develop different strategies. Let me give you an example from a presentation.
One of the tech leaders I know was giving a presentation to K-12 teachers about using social media in education in a big conference. He started his presentation by introducing “digital natives” and giving some statistical facts about how new generation uses and benefits from social media. Then he introduced major social media tools. Up to this point teachers were able to follow him but then he lost the audience by starting giving examples. You might think that giving examples is the right strategy but actually it is not if it is done right away. He missed the fact that teachers are still waiting for the answer of a very simple question; Why? His explanations in the beginning is not enough to answer this question. They are just some facts that kids’ habits are changing but how is this fact related to education?
If I were him I would follow a different way by shifting the point of view. I would ask this question first and let teachers think about it for a moment; “In your daily life do you sometimes have moments where you witness something related to your lesson and want to share it with your students?” This question does not focus on technology, it is not about behavioral change of kids. It is only about education and pedagogy. After this question comes others; “If so, can you give us an example? How did you share that moment with your students? Did you consider using technology? How do you think technology can help you? What can be the advantages and disadvantages?” etc. These questions are small steps to lead the conversation into technology tools and examples.
Technology is advancing too fast and its effects on society for today and future are observed clearly by many institutions and they are changing themsleves accordingly. Unfortunately educational institutions can not follow them since they are the most resistant ones to change. Most of the schools who are having their technology transformation nowadays are only changing their shop windows. A deeper and more realistic change can not happen until they really shift their perspective from technology to pedagogy.
In this article the phrase “Google Docs” will represent “Google Docs, Sheets and Slides”
You might have heard that Google Drive has been renewed. The major change is the new feature of editing MS Office documents. A few weeks ago we were able to open an MS Office document in Google Docs format by following Open With > Google Docs and when we do that a second editable document is created in Google Drive.
Although the procedure is easy I have experienced that some users share their MS Office files without making the conversion. This is not a problem unless you want to edit the document.
From now on we don’t need to follow these steps. In new Google Drive you simply upload your files and stop worrying about being able to edit it. Here is how you can switch to new Drive and how you can edit an Office file without converting it into a Google Doc;
Get the new Google Drive
Open your Chrome browser, go to drive.google.com and click on the Settings menu. Choose Experience the new Drive. You might not see the option to try the new look because this is not available to all users yet but don’t worry it will be available very soon. The new features of Google Drive is not the topic of this article but if you want to get an idea you can watch the following video.
Install The Extension
Getting the new Drive is not enough. You need to install an extension to be able to edit MS Office files. You might wonder why this is not done automatically. I guess Google wanted to keep this feature optional. Some users might want to have the new look but keep the old conversion process.
Click on the link http://goo.gl/4rs8ts and download the Chrome extension “Office Editing for Docs, Sheets & Slides Chrome extension” by clicking on Free > Add. After installation I suggest you close Chrome browser and reopen it.
Now you are all set. You will be able to edit MS Office files under Chrome browser so why don’t you try it now? Upload an Office file and within the Chrome browser double click to open it (or make a right click on it and click Open With > Google Docs) You will see the following. Please be careful with the filename, type and the address bar. Have you noticed Office Compatibility Mode? If you don’t see it then you will not be able to edit your file.
Here comes the bad news. It is still not possible to collaborate on an Office document in Google Drive. You still need to convert it into a Google Doc and share it in the old way.
As a prospective teacher, who is a senior student in a five year Integrated B.S. and M.S. Program in Teaching Mathematics in Faculty of Education, Boğaziçi University, my internship in Robert College has been one of the most intense experience throughout my undergraduate study. I deliberately use the word ‘intense’ since I was extremely exposed to many educational technology tools and their effective usage in classrooms. A ten-week long internship program with class observations of 8 block lesson hours per week and practice instructions of 2 block lesson hours had great impact on my teaching experiences. What makes my experiences great is that I have observed and learned how to use TI 84 graphing calculator, interactive white board, Google Apps, Web2.0 tools and many more things in classroom instruction. In this article I’d like to share some of the key facts I have observed so far.
As teachers, first thing you need to consider is to be sure that your students are ready for the tasks you will cover in the lesson. Creating an environment where students learn new concepts by building up their own conceptual knowledge brings true learning. Assessment is also a key factor to plan your lessons and should provide you enough data to understand to what extent you have reached your expected goals for the students.
When it comes to assessment, you need to think both the capability and the time efficiency of your method. As an example, in one of Mr. Firat’s classes I have seen that Google Docs could be used as formative assessment tools to provide students with immediate feedback on their performances. Thanks to BYOD, all students have access to a Google Form in which there are many questions. As soon as they answer a question they receive a feedback which shows how good their performance is by providing the statistics of performances in the class. Since Google Docs allows teachers to integrate online grading tools using scripts, such as Flubaroo, teachers can send individualized feedback to each student in seconds. Thus, students get the opportunity to monitor their progress throughout the learning process, which encourages them to take the responsibility of their learning.
I have observed that in Robert College teachers have developed many skills while integrating technology tools and applications into their curriculum. Their curiosity and enthusiasm in learning and improving themselves by developing innovative instruction strategies have made me inquisitive and enthusiastic to improve my teaching skills as a prospective mathematics teacher.
One of my colleagues has discovered the magical world of augmented reality and asked me which apps I have installed to my iPad. I have prepared a file for him and wanted to share it with you as well. If you are new to AR you can think of it as a layer you put between reality and your eyes by using your mobile device’s camera and screen. You can insert images, videos, anything you want onto that virtual layer.
Among those my favourites are Aurasma, colAR Mix, ChromVille, Anatomy 4D and Star Chart. By the way I need to say that Qrafter and i-nigma are QR Code readers and generators. QR codes are still popular so you should have these kind of apps.
Below you can find the links to the websites or iTunes pages for the apps. Most of them work in both iOS and Android.

Multitasking can be simplified as doing more than one task at the same time. This is something our students and we do regularly. We all think that there is no problem in multitasking because everything works fine and whenever we come up with an error we consider it normal. After all we are human and humans can make errors. In an overall approach the idea sounds right but there are some people who claim that multitasking increases the probability of doing errors and they have concrete scientific research results. Let me give you two examples which will clarify the situation:
1) Writing an English essay while talking on the phone with your friend (about a movie etc).
I can hear that you are saying this is a bad example because nobody does this and you are right. If two or more actions are continuous then people tend to focus on only one task. This habit is broken when it comes to driving. Many people unfortunately risk lives by texting or talking on the phone while driving.
2) Writing an English essay and checking an SMS message.
Now this example is the reason of all those discussions because the second action is not continuous. You checked the message, replied it and it took only 10 seconds. You think you can continue where you left off but actually you can’t.
While trying to study at home students get occupied by the small tasks coming from their cell phones, laptops or tablets. They think that they can manage the process but this is scientifically impossible; brain can not multitask. Below you can find some resources which support this fact.
